Usage of xlscc: sequential for loops

[Ahmed Gawish]

The official tutorial covers only the usage of unrolled loops via #pragma hls_unroll yes, it stated there is an option for sequential for loop, but I can't seem to find what pragma corresponds to that, and if I try to leave it without pragma the compiler gives me an error, so how to use sequential loops in xlscc?

In pipelined modules you can specify "#pragma hls_pipeline_init_interval " followed by the specified init interval. An example is shown in the tests here: https://github.com/google/xls/blob/main/xls/contrib/xlscc/translator_test.cc#L4052
